what i do know is that i had the problem, changed plugs and gapped them and was fine. A few other members said the same thing. I know you can run OEM plugs however i also know what PTF has on their site and they do say run NGKs gapped at 0.018-22"

For what it's worth. I roll raced a 2018 Challenger Hellcat yesterday. From a 40 mph roll, I beat him by about a foot; it was even most of the way.
The Hellcat driver was surprised. He couldn't believe my 2014 M5 CP with just BM3 Stage 1 93, everything else stock, could stay with him or beat him.
I am running on stock plugs, filters, coils, injectors and tires. I will change air filters and plugs next week to (NGK 97506 gapped at .020"), and try again.
It been fun, especially when your car is running well.
Guys, continue to learn, test and inform the group of your successes and failures.
This is how we improve the performance of our M cars.

Great Kill, now get STG 2 and really shock him. A few things to think about when considering gapping your plugs or going to colder plugs: this is a test and tune situation. Which sucks because its a pain to change them. There are several variables why there are guys on here running stock plugs with stock gaps on STG2 just fine, colder plugs with tighter gap stg2, and so on and so on. Geographically: gas quality, air density, etc will affect how your cars combustion operates. That is why a lot of people try stock plugs with stock gap first. If you have issues with your tune on stock plugs/gaps then most like it will happen when the initial heavy boost comes on at around the 3500-4000 range or way up top when the car is running out of breath. Either way those misfires would lead me to start gapping down the stock plug or change to a colder plug and gap it down. I went will colder plugs and gapped it down to .019 and that worked for me. Over the years of having performance cars I learned to listen to my tuner. In the BM3 case Halim or Dzenan will most likely answer your questions if you open a ticket on PTF site and suggest plug and gap for the proper stage tune. Also, a good idea would be to change out your coils. I had some issue with that right after my tune and I did not even have that many miles on my coils that were in before I installed the tune. You can get them pretty cheap on RockAuto (Don't get ripped off at the dealership) https://www.rockauto.com/en/catalog/...tion+coil,7060
I hope this didn't open up a huge debate at what the best coil is There is plenty of forum talk about that.

Thanks for the info BB6. I will change the plugs to the colder NGK 97506, gapped at .020"
Stage 1 93 is what I am using now (I don't want to install catless downpipes as I may trade-in for an F90 M5 CP in the near future). I also have Stage 1 93 BETA, but the Stage 1 93 ran stronger.
I enjoy running this car; it has been trouble free so far.

I have the bootmod3 stage 2 93 octane with drop in filters, down pipes, new coils and colder NGK plugs gapped to .22. Data logged it and max boost was 27.5.

BM3 Stage 2 93 requires downpipes. How much HP/TQ with 27+ lbs of boost. Have you taken it to the track or raced anyone to get an idea how quick it is.
This is good info.

Boost won’t be that high in gear on wot the 27psi would have probably been on a gearshift or when you 1st come on load

Should be 22-23psi

I know with the *blah blah blah you shouldn't drive a sports car and ride a bicycle*. I'm not against having fun but I read a study that 1 cat-less vehicle produces the same amount of hydrocarbon output as 600 catted vehicles...

I thought about adding in 200 CEL cats in the midpipes to counteract this a bit but I'm pretty sure they wouldn't get hot enough to make any difference in filter, but may kill the smell.

What to do..
mannn, do you tell her you’re a feminist as well? lol jk jk
